Atypical car driven 14,000 ݈݉݅݁ݏ a year emits to the atmosphere about 12 ݇݃ per year of nox (nitrogen oxides), which causes smog in major population areas. natural gas burned in the furnace emits about 4.6 ݃ of nox per ݐ݄݁ݎ ,݉and the electric power plants emit about 7.2 ݃ of nox per ܹ݄݇ of electricity produced. consider a household that has 2 cars and consumes 10,000 ܹ݄݇ of electricity and 1,400 ݐ݄݁ݎ݉ݏ of natural gas. determine the amount of nox emission to the atmosphere per year for which this household is responsible.

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
